Answer:

60  minutes and 70 minutes respectively

Step-by-step explanation:

Step one:

given data

We are given that Dionne can fold 175 packing boxes in 50 minutes and

Elias can fold 120 packing boxes in 40 minutes

let us find the unit rate of each of them

For Dionne

= 175/50

=3.5 boxed per minute

For Elias

= 120/40

=3 boxed per minute

Step two:

Hence,  each person will fold 210 packing boxes in

For Dionne

= 210/3.5

=60  minutes

For Elias

= 210/3

=70  minutes

Answer:

83

Step-by-step explanation:

do the math

Answer:

83

Step-by-step explanation:

Solution:

63 + 63 = 126

292 - 126 = 166

166 ÷ 2 = 83

Answer: 83

Answer:

1:2

Step-by-step explanation:

So when finding equivalent ratio in any ratio is finding a common denominator that goes to both numbers for instance:

If you have the ratio 8:16 what is the common factor that can go into both 8 and 16 equally? Well 8 can go into 8 once and 8 can go into 16 twice so lets put this into a problem:

8:16 = (8/8):(16/8) = 1:2

So our equivalent ratio to 8:16 is 1:2.

Hope this helps!!!

Step-by-step explanation:

Answer: Tavion is traveling faster than Jonathan, but Tavion is slowing down slightly.

Their initial speeds are:

Jonathan 0.667 miles per minute.

Tavion 0.833 miles per minute.

Step-by-step explanation: To find their speed, divide miles by minutes.

From the graph pick coordinates. (3,2) or (6,4) The y-values are miles, x-values are minutes.

Jonathan: 2 miles ÷ 3 minutes = 0.667 miles per minute.

For Tavion, get his initial speed from the first values in the chart.

Tavion: 12.5 miles ÷ 15 minutes = 0.833 miles per minute.

The miles do not increase exactly as the time increased. They would be 12.5, 25 and 37.5 if his initial speed remained the same.

Answer:

[tex] \boxed { - 4}[/tex]

Step-by-step explanation:

Substitute y = x-4 in the first equation.

[tex]3x - 2(x - 4) = 4[/tex]

Distribute -2 in the expression.

[tex]3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x = - 4[/tex]

Because we only want to find the value of x.

Therefore the answer is -4.

Answer:

b

Step-by-step explanation:

-7 + 4r = -15

+7             +7

4r = -8

divide both sides by 4

r = -2

Hope this Helps!!!

Answer:

r=-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4r−7=−15

Step 2: Add 7 to both sides.

4r−7+7=−15+7

4r=−8

Step 3: Divide both sides by 4.

4r/4=−8/4

r=−2

Answer:

The radius of the cone is approximately 13.4 feet

Step-by-step explanation:

The dimensions of the given cone are;

The distance from the top of the cone to the edge of the cone = 15 feet

The height of the cone = 6 feet

The radius of the cone is given by the base of the right triangle formed by the slant length, the base radius and the height which is found using Pythagoras theorem as follows;

The radius of the cone, r = √((Slant distance)² + (Height)²)

∴ r = √((12 ft.)² + (6 ft.)²) ≈ 13.4 ft. (by rounding to the nearest 10th)

Answer:

Question 9: 35    Question 10: 10

Step-by-step explanation:

Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).

Question 9:

Start with the brackets.

10 x 4 - (7 - 2)

= 10 x 4 - (5)

Then, multiply 10 and 4.

= 40 - 5

Solve the subtraction.

= 35

Question 10:

Start with the brackets.

1 - (2 - 3) + 8

= 1 - (-1) + 8

= 1 - - 1 + 8

(Two negatives = a positive)

= 1 + 1 + 8

Add the numbers.

= 10

Answer:

[tex] \fbox{x = 4.2} [/tex]

Explanation:

Using the pythangorean theorem

[a² + b² = c²], we can solve enough sides to find the proportion because both triangles are right triangles or have a 90° right angle.

Given the lengths of side a and c (the hypotenuse), we can rearrange the pythangorean theorem to solve for b.

a² + b² = c² → a² – a² + b² = c² – a² →

b² = c² – a² → b = √(c² – a²).

We are also given the hypotenuse or the side c of both triangle which are 5 to 7, which is the proportion between the triangles. We also know they are similar because they have one congruent angle and a right angle, thus the third angle must be the same. Therefore the bigger triangle has sides that are 7/5 longer than the smaller triangle. So b of the smaller triangle = √(5² – 4²) = √(25 – 16) = √9 = 3.

Now we know the sides of the smaller triangle:

a = 3

b = 4

c = 5

______

Now the only thing we have to do is match the corresponding sides, and multiply by 7/5.

This means that the sides of the bigger triangle are:

a = 3 × 7/5 = 21/5 = 4.2

b = 4 × 7/5 = 28/5 = 5.6

c = 5 × 7/5 = 7

______________

Each angle corresponds to the side opposite or across from it. Since side a is across from the congruent pair of angles we are given, the a of the bigger triangle must be x which means that x = a = 4.2.

Answer:

(10, 1)

Step-by-step explanation:

It tells you that when you translate it you add 2 to the x-coordinate and subtract 7 from the y-coordinate. This means that the point E, (8, 8), would become (8 + 2, 8 - 7) or (10, 1).

Answer:

Well, the y axis is the up and down line of the graph. Therefore, if the translation says move up six, simply add six to the y axis (ex. -6, -10 move up six: -6, -4)! super simple, right? hope this helps!

Answer:

0 People initially had the cold.

6 People will have it after 2 days.

Step-by-step explanation:

To find out how many people had it initially, plug 0 in for x (implying 0 days later.)

C= 1*3(0)

C= 1*0

C=0

Nobody had the cold initially.

To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)

C= 1*3(2)

C= 1*6

C=6

Therefore 6 people had the cold after 2 days.

Answer:

(A) The y-intercept of the line is 1.82.

(B) The number of games that could be won after 13 months of practice is 26.

Step-by-step explanation:

X : Number of Months of Practice

Y : Number of Games Won

(A)The y-intercept of the line is 1.82.

The y-intercept is the average value of the dependent variable, here the number of games won, when the value of the independent variable, here number of months of practice, is 0.

So, a y-intercept of 1.82 indicates that on average 1.82 can be won if the number of months of practice is 0.

Answer:

12x³ - 3x

Step-by-step explanation:

Given

f(x) = x and g(x) = 4x² - 1

Now,

3 f(x) * g(x)

= 3 * x (4x² - 1)

= 3x ( 4x² - 1 )

= 12x³ - 3x
